We enjoyed our stay at Kawin's place very much. It is situated in a great area of Bangkok. Lots of great restaurants in front of the building and in the area. The sky train is in walking distance and Taksin is only two skytrain stations away.
The communication before and during our stay was very good - we always got very quick and very valuable answers. Kawin and his wife have been very flexible regarding our arrival and departure arrangements.
The place is absolutely quiet and everything we needed was there.
We highly recommend Kawin's place.
